s claims. (ci. 17a-269) This invention relatesto conductor lugs, terminals or connectors, and is designed to supply an improved lug, simple in construction, of few parts and having, among others, the advantages hereinafter described.

In the drawing of one. embodiment of my invention, as comprising simply means for securing one conductor to a second conductor or terminal, selected for illustration and description herein,

Fig. l is a vertical longitudinal section of the lug on a conductor cable end, but not locked thereon;

Fig. 3, a right hand end View of the lug with the sleeve removed;

Fig. 4, a left hand end view of the sleeve with the locking pin in section for illustrative purposes only;

Fig. 6, a View similar to Fig. l, of a modified form of device;

Fig. 7, a View similar to Fig. 2, of a modied form;

Fig. 9, a cross-sectional view on the line 9 9, Fig. 6;

Fig. 10, a similar view on the line Ill-I0, Fig. 7;

Fig. 1l, a side elevation of the neck with the sleeve removed; and

Figs. 12 and 13 show modied forms of theconductor body adapted for receiving a plurality of conductor ends.

My novel lug, as shown, Fig. 1, comprises a body section I, herein hexagonal, of convenient length, with a suitable locking end post or flange 2, at in this case, bored at 3, to receive a locking bolt, screw or other means for securing the lug to one or more lugs, terminals or conductors of any kind.

The body carries on its opposite end a neck 5 with a concentric, external sleeve engaging thread 6 and an interior conductor locking eccentric thread 7. The neck 5 carries a sleeve 8 with an interior, concentric thread 9 for a portion of the length to engage the thread 6, and is provided for the balance of its length with an interior eccentric thread I 0. The body has, at a suitable point thereon,-Fig. 3, a post or other lock member II, which is received in a cooperating member or groove I2 on the adjacent end of the sleeve, Fig. 2, to prevent accidental removal of the member 8 from the member 5.

With the eccentrically and interorly threaded section of the sleeve properly positioned on the neck 5, as in Fig. 1, there will be a straight passage through the sleeve into the neck, to receive a conductor, as a bared cable end 20.

When in that position the conductor end may be inserted into the sleeve and bored neck without difficulty, and locked therein by a partial 10V turn of the. sleeve 8 clockwise, Fig. 3, which causes the edge of the bore of the sleeve to bind on the lower face of the conductor and the eccentric thread l thereon, tov cut into the conductor, and at the same time to wedge the op- 15 posite side of the end of the conductoraganst the interior thread I of the neck which cuts into it with the result that the conductor is slightly offset between these threads, Fig. 2, Yand locked therein very rmly.

In Figs. 6-11, I have shown a modied form of lug wherein the neck 5 has a sleeve engaging concentric thread 6, and is eccentrically bored, to receive a conductor. The bore is eccentric to the degree that, at one point, Fig. 11, the wall of the neck 5 is so thin that the bottom of the thread 6 is cut away in several turns of the thread, leaving an opening I3 into the bore.

On the neck 5 is a sleeve I4 with an interior concentric thread I 5, and at one point, Fig. 6, the tops of the threads are cut off as at I6, Fig. 7, to cooperate with the bottomless section of the thread 6 of the neck 5, so that when the sleeve is so positioned on the neck, Fig. 6, the latter will present a substantially smooth bore to receive the conductor end. The neck has on its outer end, Figs. 6, 7, a ring I1 xed thereto to render the sleeve captive so that it cannot be accidentally lost.

I n use, with the sleeve I4 in described position on the neck 5, see Fig. 6, the conductor, as a bared cable end 20 is thrust through the sleeve and into the neck and the sleeve given a partial turn clockwise to cause the full thread section l5 of the sleeve to move opposite the bottomless secti-on of the thread 6 of the neck where the full thread I5 of the sleeve will extend through the opening I3 of. the neck and cut into the surface of the cable and thus lock it securely in the lug.

In the meantime, the shallow thread or bottomless section of the sleeve thread 6 has moved about the neck 5 and, Fig. 10, will leave at one point a shallow space I8 between the two engaged threads 6, I5.

There are many forms of lugs or connector terminals on the market today. Many of these are of complicated construction, including several separate parts, any one of which, if lost, or mislaid temporarily, delays the work of the operator.

The common and long used method of soldering the connectors has always an element of danger, requires the provision of a furnace, needs ample room, and is not always reliable.

My novel lug as described is simple in construction, of few parts, neither of which can become detached by ordinary usage, is simple and effective in application and reliable. It can be used in close quarters where space is limited, the workman needs no helper and permits of more compact assembling of conductors than any other known to me.

Obviously, Figs. l2, 13, the body of the lug may be of any size, external outline, and have more than one conductor neck 5 and sleeve 8 or I4 for use under differing circumstances.

My invention is not limited to the precise embodiment thereof herein described and illustrated.

I claim:

1. A device having provision for connection thereto of an electric conductor having, in combination, a pair of members one screw threaded on the other, said members being so formed as to provide in one relative rotative position thereof a conductor receiving bore which is eccentric to the common axis of the screw threaded portions of said members and which at one lateral side thereof cuts through the cooperating screw threads of said members Without removing the top portions of the screw threads of the inner member.

2. A device having provision for connection thereto of an electric conductor, comprising an exteriorly screw threaded member formed with a longitudinally extending conductor receiving bore positioned eccentrically thereof and laterally opening into the spaces between adjacent turns of the screw threads of said member without removing the top portions of said screw threads, an interiorly screw threaded member screw threaded on said exteriorly screw threaded member, the interior screw threads of said interiorly screw threaded member being of. reduced height at one side thereof to permit insertion of a conductor into said bore when that portion of said interior screw threads is in registry with the lateral opening of said bore.

3. A device having provision for connection thereto of an electric conductor, comprising an exteriorly threaded member, an interiorly threaded member screw threaded on said exteriorly threaded member between the ends thereof, means operatively carried by said exteriorly threaded member to limit the movement thereon of said interiorly threaded member in opposite directions, said exteriorly threaded member having a longitudinally extending conductor receiving bore formed eccentrically thereof and opening laterally thereof into the spaces between adjacent turns of the exterior screw threads of said member without removing the top portions of said screw threads, whereby when a conductor is inserted into said bore one lateral side of the conductor will project into the spaces between adjacent turns of the exterior screw threads of said exteriorly threaded member, the interior threads of said interiorly threaded member at one side thereof being of reduced height to permit insertion of said conductor into said bore f5 when that portion of said threads is in registry with the lateral opening of said bore.
